To 'all lwhom it may concern.' i

Be it known that I, ARTHUR C. JcHNs'roiv,

cation.

\My invention rela-tes to certain imip'rove-l 'ments in apparatus for handling coal and.

like material.

The 'apparatus is particularly adapted for'. lading vessels with coal, 'although it will be understood that the invention can be' used -This frame has wheels adapted to 4rails 'g for 'loading coal orntoothter carriers.

One object of theinvention is to simplify".

' the construct-ion lof this type .of apparatus and to construct the mechanism s'o that one vor more vessels vcan 'be loaded from a given` bulkhead. The horizontal portion n is ex- 'point, While moored lata dock.

A further- `object ot .the invention is tog 'construct 'the Iapparatus in two sections so f that it wil'laccommodate itself to the vessel l be raised and lowered. Depending from being loaded.

in the accompanying 'dra-wings: `Figure l, y

Ais a diagrammatic plan view illustrating my invention as located on a dock in which the birlkheads are arranged, one atan angle to y another; Fig. 2, is an lenlarged diagrammatic view in elevation ;'Fig. 3, is a diagrammatic view illustrating the invention applied to a dock having a segmental bulkhead, and Fig. 4, is a diagrammatic view of a modification of .the invention 'applied to a dock having a straight bulkhead.

A is the dock, in the present instance, having three bulkheads a, a', a2, one 'arranged iat an angle to another.

scribed.' The bulkheads 'are of suiicient length so that a comparatively long vessel` the hopper. In the present instance, D are Each bulkhead isv the same -distance from :a point m, which is` the pivot for the conveyer hereinafter de-V i from the storage tracks D to the dumpin appara-tus C 'and the contents discharge linto the hopper, after which theyare 1transferred from the tracks Z and e to the storage tracks for empty oars.

I are four conveyors, 1n the present in'- stanoe. These conveye'rs are Epivoted at the point ai and terminate ait their outer end at z'ldirectly over the horizontal portion n of a an auxiliary or boat ldading convey'er N. .Each conveyer I is ma-de of a frame supporting an endless belt, which carries thecoal from the hopper to the disdharge end i.

on 'which t'fhe conveyer is supported so that each conveyer can readily swing on its pivot. The auxiliary. conveyer consists of a frame having wheels adapted to 'rails -f-f near the tended under the overhang'ing end 'z' of the pivoted conveyer I, while the 'outer end n2 .is pivoted at 'mto the frame so that it can the outer end of the section 'n2 is a 'leg s, which can enter the Hold of the vessel through the hatchway,l when 'the section n2 is lowered. By this construct-ion the c'oal f can be directed to any point 'desired-in the vessel.

The auxiliary conveyer AN 'can 'be propelled by power .or by Hand, 'as desired, and the pivoted conveyer I can also be moved either by power or 'by hand. By providing a series of pivoted conveyers, as shown, to receive coal from one hopper a number 'of vessels can be loaded `at the saine time and `the 'ccafl can discharged into' a vessel through two or more hatchways In 1, l have shown. a vessel P having without havingfto adjust either of the two conveyors 'except-to move the auxiliary conveye'r on itstrack to aline with the ifiaftchvvay of the vessel to be vleaded and tfo swing the conveye I in position lse that its end wiil i extend over the horizontal portion of the conveyer N.

- While in" Fig. l, I have shown a wharf having a series of bulkheads arranged at an angle, one to another, in Fig. 3, I have illustrated a segment-albulkhead and vessels can" h: located at any point desired, while in Flg. 4, I have illustrated a straight bulkhead. In this instance, the pivot point is far enough from the bulkhead so as to lallow the pivoted conveyer to. swing and'yet -discharge into the horizontall portion of the supplemental conveyer. In4 this instance the horizontal portion of the supplemental conveyer can be made, if desired, of a greater length than that illustrated in the arrangement shown in Figs. land 2.

It Will-be seen that I am enabled to provide a simple and effective apparatus for handlin coal in large quantities; the coal being de ivered at a cent-ral point from cars and transferred by means of conveyers to a `vessel at a bulkhead of a dock and as the bulkhead will vary according to the location of the wharf and 'the railroad terminal lifacilities, the apparatus may necessarily be modified without de arting from the essential features of the invention. j

If a vessel, such as indica-ted by the letter I?, 1s to be loaded with coal,it can be han# dled by conveyers; one or more of the auxiliary conveyers N being located in position opposite the hatchway or hatchways and the pivoted conveyers I are shifted so that the ischarge endwill overlap the portions n of the auxiliary conveyers. The cars, one

after another, are then transferred to the dumping apparatus C and their contents lleg into'the hold of the vessel.

discharged intothe hopper B. A chute leads from the hopper toeach conveyer I and the flow offcoal through the chute may be regulatedA ili 'any manner desired so that W en power 1s appliedthe coal is carried by the conveyer belt, in the present instance,

vand discharged onto the belt n of the auxiliary conveyer N and discharged through the Thls leg can be moved on its pivot to direct the coal to any point desired withinv the hold. The portion n2 of the conveyer N-with the le s can be raised clear of the vessel when it is desired to shift the auxiliary conveyer from one point to another or to allow the vessel to leave thewharf after being loaded. In small plants, a single pivoted conveyer I and a single auxiliary conveyer N may be used, but 1n large plants I prefer to duplicate these elements, as shown in Fig. 1 of the drawings.

While I have described the invention as' another, and while I have described the auxto the hopper an horizontal plane; an inde endent auisullaryl iliary conveyer N as having a horizontal section n', .this horizontal section may be slightly inclined, Without departing from the spirit of my invention.

I claim:

l. The combination in apparatus for handling coal, or like material, of a hopper; a conveyer arranged to swing in a horizontal plane; an independent auxiliary conveyer arranged to receive material from the free end of the main conveyer and to discharge it into a vessel, or other carrier; and a frame on which the auxiliary. conveyer is mounted, said frame'being movable independently of the main conveyer.

2. rIhe combination in apparatus for handling coal,`of a ho per; a conveyer pivoted arranged to move in a conveyer having an exten ed receivin portion over which the end of the pivote con-4 veyer projects; and a frame on which the auxiliary conveyer is mounted; said frame being movable independently of the, main conveyer.

. 3. The combination in apparatus for handling coal, of a hopper; a series of conveyers pivoted at the hopper; a bulkhead; av

track at the bulkhead; a series of auxiliary conveyers mounted on the track and arranged to receive material from the pivoted conveyers and to deliver said material to vessels -at the bulkhead.

4.' The combination of a hopper; a conveyer pivoted at the hopper; a wharf having two or more bulkheads arranged one at an angle to another; an auxiliary conveyer at the bulkhead arranged to receive material from the pivoted conveyer and to deliver said material to a vessel at one of the bulkheads.

5. The combination of a hopper; a wharf having two or more bulkheads, one arranged at an angle to another; a series of conve ers pivoted at the hopper; a track extening along the bulkheads; a series of auxiliary conveyers mounted on the track and each' los having'an extended horizontal portion at the rear over which the end of the pivoted conveyers project and each having a pivoted extension overhanging the bulkhead so as to disciarge materlal lnto a vessel at the bulkhea 6. The combination of a bulkhead; a conveyer pivoted at a point distant from the bulkheadand arranged to swing in a horizontal plane; a hopper at the pivot point for discharging coal into the conveyer; a track at the bulkhead; an auxiliary conveyer mounted on the vtrack and having a rearwardly extending horizontal portion over which the discharge end of the pivoted conveyer projects and havin a projecting vportion overhanging the bul head so that coal delivered from the hopper will be transferred by the pivoted conveyer to the auxiliary conveyer and from the auxiliary conve er to a vessel at the bulkhead.

The combinationin apparatus for handling coal, of a Wharf having an extended bulkhead a pivoted conveyer; a hopper some distance backl of the bulkhead; a belt conveyer pivoted at the ho per and laterally movable; a track at the bulkhead; an en less auxiliary conveyer mounted on the track and having a rearwardly extending horizontal portion underlapping the discharge end of the pivoted conveyer and having a pivoted section projecting beyond the bulkhead; With a leg suspended from the end of 15 the said pivoted section so that coal discharged into the' hopper will be transferred by the conveyers into the hold of a vessel at the bulkhead.

In testimony whereof, I have signed my 20 name to this specicaton, in the presence of two subscribin witnesses.
